- y To'all wkom it may concern:

" Be it known that 1, WILLIAM ELMEN- v- J :THALER, residing at Cleveland in the county 1 of Cuyahoga and State ofaOhio, have 1n- 5 vented certain new and useful Improvements tin Direction-Indicators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 10 it appertains to make and use the same.

This invention has'for its object to provide a direction indicator for motor vehicles including two independently and electrlcally operable sets of signals, one set 'being de- .slgned for use during the day and theother I set being designed for use during the night.

v With this andother objects in View, the invention consists in the novel construction,

-. arrangement and formation of parts aswill ings, in which I p a Figure l representsa I up direction indicator applied to use on'aj motor x "the indicator-i '""'"Referring to.

be hereinafter specifically described, claimed and illustrated in the accompanying drawa it: ofi the rear elevati vehicle, Fig. 2 represents ,a hori'zcntal sectional view, partly broken'away, throughthe "indicator; Fig. '3 represents a diagrammatic view of the electrical circuit for the indicator.

"Partitions 7 are arranged be- :g tween-the 'partition'16 and the rear wall of the'rhousin'g 6 and divide the latter into three when-communicating lamp chambers 8;

14 secured in suitable apertures formed in the rear wall 'of the housing 5.

A pair of solenoids 16 arearranged, one

above the other, between-the-central parti tion; 6 and the rear wall of the body or housing 5 and are provided with sliding armatures.l7 slidable through the opposite open ends of said solenoids. Right andleft hand' signal arms 18 and 19, respectively, are

' pivotally mounted on the central partition 6 and are movable. on horizontal axes 20. A lever 21 is pivotally secured at 22 to the partition 6 and is provided in its'upper end with a longitudinally elongated opening 23 in which is mounted a pin 24: carried by the armature 17 of the upper solenoid. The

lower end of the lever 21 is connected with the right hand signal arm 18 by an angular link 25. Y'An angular lever 26 is pivotally hand signal arm 19, adj acentthe pivotalaxis ofthe latter, by a link 29.

The indicator is electrically operatedby a battery A, or other suitable source of-elec- 'tromotive force, which is connected by a conductor B with a switch arm 1C movable over stationary contacts D and E. The contact E is connected with the right and left hand lamps 12 and 13, respectively, by a conductor F, andthe contact E is connected with the right and left hand solenoids 16 by a conductor G. A conductor H connects the battery A with a second switch arml, and a branch conductor J connects the conductor H with another switch arm K. The switch I is movable over contacts L and M, thecontact L being connected by a a conductor N with the right hand lamp 12 and the contact M being connected with the left hand lamp 13 by a conductor 0. The switch arm K is movable over stationary contacts P and Q, the contact P being connected with one solenoid 16 by a conductor R and the other stationary contact Q, being connected with the other solenoid 16 by a conductor S. The

switch arms C, I and K are'preferably mounted withina suitable switch box T arranged conveniently near the driver of the vehicle to which the indicator is attached, and said switch arms I and K are prefertrated in Fig. 1, and the license tag 11 is preferably arranged at a point adjacent the upper lamp chamber 8, whereby the rays of light from the tail lamp 9 will be reflected thereon and render the same clearly visible at night. During the day, the switch arm 0 is moved to the right to engage the contact 'D, thus closing one side of the circuit from the battery A to the solenoids 16 through the conductor G.. In normal position, the signal arms 18 and 19 assume the inclined position illustrated in dotted lines in Fig. 2 and the armatures 17 are partially withdrawn from the solenoids 16. When the driver of the vehicle desires to turn to the right, the turn button U operating the switch arm K is rotated to engage sa1d switch arm with the contact Q, thus closing the circuit from the battery. A through the conductor H, branch conductor J switch arm, K, contact Q, conductor S, solenoid 16 operating .the right hand signal arm 18, conductor Gr, contact D, switch arm G and conductor B. When the solenoid 16 operating the right hand signal arm 18 is energized, the armature 17 is drawn inwardly, rocking the lever 21 on its pivotal axis 22 and raising the si nal arm 18 to a horizontal position throug the angular link 25. When the circuit to the solenoid is broken the weight of the arm 18 throws the latter downwardly withdrawing the upper armature 17 from its solenoid 16 through the link 25 and lever 21. When the driver of the vehicle intends to turn to the left, the turn button U operating the switch arm K is rotated to engage said switch arm K with the contact P, thus closing the circuit'to' the solenoid 16 operating the left hand signal arm 19 from the battery A through the conductor H, branch conductor J, switch arm K, contact P, conductor R, solenoid '16, conductor G, contact D, switch arm.C and conductor B. The

lower solenoid 16 being energized, its armature 17 is drawn inwardly rocking the angular lever 26 upon its pivotal axis 27 and raising the left hand signal arm 19 to a horizontal position through the link 29. During the night, when the signal arms 18 and 19 are not clearly visible, the switch arm Tis swung to the left to engage the contact E and thus, when the turn button U operating cm" of this pat ent may be obtained for the switch arm I is rotated, the electrical circuit to the lamps 12 and 13 is closed to indicate the intended course of the vehicle.

What I claim is:

1. A direction indicator comprising a housing having a partition therein, lamps arranged on one side of said partition, signal arms pivotally mpunted in said housing, electro-magnetic means for operating said signal arms, an electric battery, a pair of spaced relatively stationary contacts, an

nection between said switch armand the opposite side of said battery, the second-mentioned arm being movable over the second pair of contacts, a third pair of contacts, an electrical connection between each of the contacts of the third pair and the electromagnetic means controlling one of the signal arms, a switch arm movable over the contacts of the third mentioned pair, and an electrical connection between the third mentioned switch arm and the opposite side of said battery.

2. In a direction-indicator, a housing, a pair of signal arms pivotally mounted in said housing and projecting outwardly of the opposite sides thereof, solenoids arranged one above the other in said housingand centrally below said signal arms, armatures slidably associated with said solenoids, a lever pivotally secured in said housing below the armature of the upper solenoid, and being pivotally connected with the latter, an angular link connecting said lever with one of said signal arms, an angular lever pivotally secured in said housing above the armature of the lower solenoid and being pivotally connected with said armature, and a link connection'between the other signal arm and the angular lever.

In testimon whereof I aflix in presence 0 two witnesses.
